Hi Mcdade.
I haven't actually had a psychosis (my prob was clinical depression) but I was married to a lovely man who had psychotic episodes. he described his experiences just as you have-feeling 'flat', no energy and boredom. He was on Depixol depot injections and for a few days afer them, all he wanted to do was sleep. He was ok then, until a week before his next injection was due, when he became restless and a bit off-centre again. He asked to try oral medication but would then think he was cured and would stop taking them. These episodes of his would come and go-he wasn't always in the 'ill' phase. We would have a laugh together about the ideas he had when he was 'unwell'-one day, he sat out on a roof at 3am playing his trumpet and another time, walked around with plastic bags on his feet because 'We always do that in the S.A.S.' So in his case, there were lighter moments! He did voluntary work and enjoyed it although sometimes he didn't feel like going! We eventually divorced and this was mainly because my depression worsened and we weren't coping. He and I are still the best of friends though.
You sound like an intelligent and perceptive person Mcdade. You say you feel 'stupid' but no way are you stupid. I haven't looked online but there may be some useful forums where you could chat about the way you feel and get some good ideas by talking to other people who are in similar situations.
I hope that you soon feel better about things. I wish you all the luck in the world huns.
Best wishes, Maz xx
